that pr requires chip turn on CONFIG_DRIVERS_BLUETOOTH to use bluetooth,
but not all defconig enable this option, so let's map bt_driver_register
to bt_netdev_register in header file in this case, and revert the unnessary
change in the related chip and board folders.

When sig dispatch do up_schedule_sigaction, need to make a new frame to
run arm_sigdeliver. But the exception_direct cannot handle xcp.regs as
we are using c-function exception handler.
Need to use exception_common to handle SMP call.

Implement PIC loading in armv8-m qemu,
for example: load address-independent AP ELF in the bootloader,
and the text segment in AP ELF is XIP,
no need to apply for memory and modify it.
Two config:
bootloader abbreviation bl:
use romfs to load ap elf, use the boot command to parse and jump to ap
application abbreviation ap:
run os test
We need to compile ap first, then compile bl.
compile step:
./tools/configure.sh mps3-an547:ap
make -j20
mkdir -p pic
cp boot pic/.
genromfs -a 128 -f ../romfs.img -d pic
make distclean -j20
./tools/configure.sh mps3-an547:bl
make -j20
run qemu:
qemu-system-arm -M mps3-an547 -m 2G -nographic -kernel nuttx.bin \
-gdb tcp::1127 -device loader,file=../romfs.img,addr=0x60000000
nsh> boot /etc/boot
ap> ostest

Need to start up a new to setup special registers use
`arm_pic_setupxcp`.
Note that CONFIG_BUILD_PIC compiles the entire NuttX image
as position-independent(PIC), enable CONFIG_PIC to load PIC
application code.

Added a flash driver for the STM32G4 series. The primary change here is
the addition of stm32g4xxx_flash.c. This file uses the STM32L4 flash
driver as a template. The primary difference is the accounting for dual
banks with different page sizes.
Fixed error while building b-g474e-dpow1/buckboost. It was possible (technically) to have page be used uninitialzied. Changing the if statement to default to using a flash_page_size == 2048 fixes this issue.
In armv8m the FPSCR[18:16] LTPSIZE field must be set to 0b100 for
"Tail predication not applied" as it's reset value.

When neon is enabled, compiler may optimize 64bits access to vstr, that
will cause data aborts.
Split 64bits access to double 32bits access for GIC_IROUTER/GICR_TYPER,

Need to save the regs firstly in case syslog triggers another crash.
Otherwise we may loose the register contents for the first exception.
